Multi-Factor Authentication
What is Multi-factor Authentication (MFA)?
Multi-factor Authentication (MFA) is an authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN. Rather than just asking for a username and password, MFA requires one or more additional verification factors, which decreases the likelihood of a successful cyber attack. While important, usernames and passwords are vulnerable to brute force attacks and can be stolen by third parties. Enforcing the use of an MFA factor like a thumbprint or code number means increased confidence that your organization will stay safe from cyber criminals.

What are the privacy issues? What does your work collect about your phone? Do they have to install something?
